.Sh DESCRIPTION
.Fn X509_STORE_new
allocates and initializes an empty X.509 certificate store
and sets its reference count to 1.
.Pp
.Fn X509_STORE_up_ref
increments the reference count of
.Fa store
by 1.
.Pp
.Fn X509_STORE_free
decrements the reference count of
.Fa store
by 1.
If the reference count reaches 0,
all resources used by the store, including all certificates
contained in it, are released and
.Fa store
itself is freed.
If
.Fa store
is a
.Dv NULL
pointer, no action occurs.
.Sh RETURN VALUES
.Fn X509_STORE_new
returns a newly created
.Vt X509_STORE
object or
.Dv NULL
if an error occurs.
.Pp
.Fn X509_STORE_up_ref
returns 1 for success and 0 for failure.
